PRODUCT DETAILS
Description
ATOM DTU LoRaWAN915 Kit is a programmable data transmission unit (DTU) designed for LoRaWAN applications operating at the 915MHz frequency. It utilizes the ASR6501 scheme, which enables long-distance communication, ultra-low power consumption, and high sensitivity.
Similar to the previous description, ATOM DTU LoRaWAN915 integrates the LoRaWAN protocol stack and utilizes a serial communication interface controlled by AT commands. It can function as a collection node, allowing for data collection and management by connecting to multiple gateways.
To enhance communication quality and signal stability, the module features an SMA external antenna interface. This allows for the connection of an external antenna, improving the range and reliability of wireless communication.
Different from traditional DTUs that typically support only data transparent transmission, the ATOM DTU series adopts a more open architecture design. The ATOM LITE controller provides programmability, allowing users to modify the program as needed for their specific business requirements. The module also includes a variety of interfaces such as RS485, I2C, and custom interfaces, which facilitate the expansion and rapid integration of sensors and actuators.
ATOM DTU LoRaWAN915 is designed to be embedded in various industrial control sites and features a guide rail clamping structure for easy installation. It provides a cost-effective solution for small data collection nodes in industrial applications.
Note:
This module supports US915 band plan only. NOT supports AU915.
